The commission opened a statutory inquiry into Save the Children UK two weeks ago to look into the charity’s handling, reporting and response to claims of misconduct and harassment by senior staff.

In February it was revealed that the charity had investigated chief executive Justin Forsyth in 2011 and 2015 over allegations that he sent inappropriate texts and made comments to female staff members.

There have also been allegations about Brendan Cox, the charity’s former policy director and the widower of the murdered MP Jo Cox. These concerned alleged inappropriate behaviour towards women before he left the charity in 2015.

Sir Alan Parker, the chair of Save the Children International, resigned last night because of allegations that complaints about the behaviour of senior staff members had not been properly handled.

In a statement released today, the commission said: "The commission would like to hear from anyone with information which is relevant to the inquiry including misconduct allegations, complaints or incidents involving the charity, and has set up a dedicated email address for anyone wishing to contact or submit evidence to the inquiry."
